Rear Magnetic Encoder: Inspection
WARNING: This page is about a different car, the 2022 Subaru WRX. However, it is still accessible from the selected car via links, so may be relevant.
Visually check the rear magnetic encoder for any damage. If necessary, replace with a new rear hub unit bearing.
NOTE:
Because the rear magnetic encoder is integrated with rear hub unit bearing, replace the rear hub unit bearing with a new part if there is any defect found on the rear magnetic encoder.
